ABSTRACT:
The present invention comprises a Global Positioning System (GPS) Wide Area Augmentation System (WAAS) retrofit receiver. In one embodiment the present invention includes a receiver adapted to receive WAAS messages via an antenna. The receiver is further adapted to translate the WAAS messages into RTCM SC-104 standard messages and transmit the messages to an external GPS receiver via a communications link. In so doing, the external GPS receiver is able to utilize the WAAS messages without modification of the external GPS receiver.
